27 Claims.

The present invention relates to a new mechanism for baling loosematerial such as straw, hay, cornstalks, rice straw, sugar cane, and thelike, being concerned more particularly with the baling of vegetablestalks of the lcharacter indicated. 4While this invention is illustratedin connection with a combined harvester-thresher, I desire it understoodthat this is merely for the purpose of illustration, my invention beingcapable of use also with machines sometimes referred to as stationarythreshers. This machine is also adapted to corn harvesters and riceharvesters, as well as for the baling of hay and other small grainstalks than those mentioned above. I shall therefore use the term stalksbaling machine" in a generic sense meaning a machine for baling any ofthe above mentioned vegetable substances or any others of a similarnature. I also desire it understood that, unless specifically limited bythe terms of the claims, they are intended to cover both stationary andportable machines.

In order that there may be no misunderstanding as to the meaning ofterms used, certain terms will be dened or explained. The term combineis used in its usual trade sense as referring to a combinedharvester-thresher. The terms bundle and sheaf refer to a collection ofunthreshed stalks which have been brought together into approximateparallelism and tied with suitable means, such as wire, twine, or otherbrous or stranded material, as has long been done by grain binders,while the term bale hitherto has referred to a similarly tiedaggregation of stalks having no particular arrangement but generally`more or less heterogeneously arranged. In the present instance, thestalks are arranged by the auger aswill be referred to here- Combineshave always been equipped withmeans for distributing the straw over theeld after the grain has been threshed. This is uneconomical and a greatwaste since there is much food value in the grain which goes out withthe straw and chaff, and in the straw itself. By binding up this straw,chaff and grain, a large percentage of this food value is saved. Nodevice (Cl. D- 20) has been heretofore produced `which would operate tobale the straw coming from a combine.

Among the objects of this invention are to provide a new apparatus forbaling; to provide an improved apparatus for baling vegetable stalks; toprovide an improved apparatus for baling straw which will serve also tosave the bulk of the chaff and grain which is ordinarily lost when usingprior methods of vcollecting straw; toA provide a newvapparatus for thebaling of vegetable matter which can be manufactured and sold for afraction of the cost of prior apparatusl for simi- -lar purposes; toprovide a combine equipped with an automatic baler; and such furtherobjects, advantages and capabilities as will hereafter appear and as areinherent in the construction disclosed herein. My invention furtherresides in the combination, construction and arrangement of partsillustrated in the accompanying drawings and, while I have shown thereinwhat is now considered the preferred embodiment of this invention, Idesire the same to be understood as illustrative only and not to beinterpreted in a limiting sense.

Reference will now be made in greater detail to the annexed drawings forthe further description of this construction. As illustrated in Figs. 8,9, and 10, this apparatus comprises essentially a receiving hopper, anauger for arranging and compressing the vegetable matter which is to bebaled, a collection chamber, a needle, compressor means, and knottingmechanism. In order to get a preliminary idea as to the functioning ofthe apparatus, before proceeding with the detailed description thereof,I will outline in a few words what takes place.

First let us assume that we are operating a combine and that the strawis being delivered from the rear end thereof in the usual manner exceptthat the present apparatus is substituted for the straw scatteringmechanism quite commonly used with such machines. As the straw is beingdelivered from the combine, it is fed into the hopper of my apparatus,the auger of which is rotated about its longitudinal axis in thereceiving hopper. This auger compels the straw to be delivered into thecollection chamber in more or less of a spiral form but distributed welltoward the outside of said chamber. Among the straw and chaff fed intothis apparatus by the combine, there is more or less loose grain whichis ordinarily lost. In the present apparatus, this loose grain, alongwith the chaff, is collected amongst the straw and is bound into thebale when the bale is formed and tied. As the straw is forced throughthe collection chamber, or beyond the baler, while and after being tied,it causes actuation of a tripping mechanism, resulting in the actuationof certain compressing members, herein referred to in connection WithFigs. 8 to 17, inclusive, as harpoons or in connection with Figs. 1 to6, inclusive, as compression jaws. they travel, they push the strawahead of them and into engagement with a gate. This gate and theharpoons together compress 'the bale so that the needle may draw thetwine tightly around the same, resulting in the latter being tightlybound when released from the apparatus. After the knot is tied, theneedle,vthe gate, and the harpoons return to the positions shown in Fig.8. However, during the compressing and tying operation, the straw whichhas been delivered to the receiving hopper has been forced by the augerinto the collection chamber, preparatory to the making of the next bale.In the structure shown in Figs. l to 6, inclusive, the harpoons arereplaced by a different type of compressing members having similarfunctions.

As illustrated in the present drawings, this construction comprises anelongated box I having at one end thereof a hopper 2 for the receptionof the straw, grain, hay, or other vegetable stalks with which thedevice may be used. As indicated heretofore, this device is illustratedin connection with a combine and the hopper 2 is therefore below thedelivery end of the combine, from which the straw is discharged from themachine. A shaft 3 passes through bearings 4 and 5 and is supportedthereby to be rotated about its longitudinal axis by the belt 6 passingover the pulley .l, this belt being driven by the puley 8 mounted upon adriven shaft 9 of the combine. The shaft 3 extends through the hopperchamber and has mounted thereon and suitably secured thereto a tubularmember Ill about which is a spiral blade Il. This has a substantiallyuniform diameter and pitch except at its forward end which is somewhatenlarged, as illustrated in Fig. 8, and may have a less pitch at itsforward end than at its rearward end. The purpose of this is to give adecided tendency to the vegetable stalks to be forced to a right angleto the axis ofthe auger and thus to be put into the bale spirally.

I'he end of the flight of the spiral conveyor may be sloped backwardlyor forwardly as desired so that the bale will not have a tendency tobuckle and fall out of the band. A spiral web I3 is secured to theinside of the hopper chamber and partly surrounds the auger, extendinginto the collection chamber, located just forward from the hopperchamber. 'Ihis spiral web tends to vprevent the vegetable stalks fromrotating around with the auger without advancing toward the collectionchamber. It also has a tendency to hold the vegetable stalks in contactwith the auger so that they will be pushed forward thereby.

'Ihe rotation of the auger tends to throw the vegetable bers into aspiral. Thus the finished bale is similar to a long auger whose ightshave been compressed together. Furthermore, a few of the stalks will bearranged at various angles to the spiral layer. Thus, the bale whencompleted will be quite thoroughly bound together so that there will belittle danger of its falling apart.

As the straw collects in the collection chamber Il, (see Fig. 8) it isdistributed and packed by the auger Il and forced past a measuringdevice I5 (at one side of the tying chamber vMa) which is actuated bythe straw or other stalks as they are advanced toward the discharge end.The location of this measuring device I5 is shown most clearly in Figs.8 and 10. As indicated in These are pushed forwardly and, as

the latter figure, this device is carried on a shaft i6 extendingvertically at one side of the collection chamber. At its lower end, thisshaft carries a tripping dog |1, shown in Fig. 8 as lust in the act ofengaging the finger |g6, pivoted at i9 upon a bracket |9a, and havingconnection with the link 20 whose opposite end 2| is connected to abracket 22 (see Figs. 9 and 10) iixedly connected to a slide 22acarrying the stop ngers 23 and 24 (Fig. 8). A clutch operating arm 26,connected with the clutch 26, cooperates with the fingers 23 and 24 toassist in controlling the functioning of the machine, as will be setforth in more detail hereinafter.

The clutch 26 is carried by a shaft 21 which has loosely mounted ontheladjacent end thereof a crank arm 26. This crank arm is connectedwith v the clutch 26 so that when the latter is caused to rotate withthe shaft 21 it will cause the crank arm 28 to rotate also. This crankarm is connected pivotally at 29 with a link 3|! which is in turnpivotally connected at 3| to a crank arm 32 carried by a shaft 33. Apair of crank arms 34 are mounted upon the shaft 33 at opposite sides ofthe hopper compartment and are pivotally connected at 35 with the rods36. hereinbefore referred to as the harpoons. As shown most clearly inFigs. 9 and l1, the harpoons extend through guides or covers 31 mountedupon opposite sides of the collection chamber. The latter is providedwith openings in its opposite sides for the harpoons to extend throughand reciprocate in,

As shown most clearly in Figs. 11 and 12, the forward ends of the rods36 are chambered on their inner faces for the reception of the springs39 which are connected at one end to the rods 36 and at the opposite endto the harpoon fingers 4I). Thesengers thus are drawn inwardly towardseach other so as to engage `the vegetable matter and force the saineforwardly as the harpoons are advanced by rocking of shaft 33 and thecrank arms 34. It will be seen from Fig. 8 that, when the harpoons 36are fully retracted, the fingers 4|l are brought back entirely clear ofthe collection chamber so as to permit the vegetable matter to be pushedforwardly entirely free from any obstruction. While the parts are in theposition shown in Fig. 11. the collection chamber is entirely free forthe vegetable matter entering the hopper 2 to be forced forwardly by theauger, thus making the device a continuously operating one. The meansfor operating the shaft 21 and the harpoons 36 consist's of apair ofbevel gears 42 and 43 mounted respectively on the shafts 21 and 3.Therefore, since the shaft 3 is operated continuously, the bevel gearswill likewise be operated continuously, thus giving continuous rotationtothe shaft 21. It will therefore bel seen that when the crank arm 2B isclutched to the shaft 21 it will be rotated and the harpoons will beactuated. either forwardly or reversely depending upon that portion ofits cycle of operation which the crank arm 28 is making.

A shaft 44 `(see Figs. 14 to 16, inclusive) is mounted in the frame workparallel to the shaft 3 and these two shafts have upon their outer endssprocket wheels over which passes a sprocket chain 45 for transmittingmotion from the shaft 3 to the shaft 44. The shaft 44 car/fries theroller 46 over which passes an apron 41 which also passes about a roller49 carried by a shaft 49, supported by the framework of the machine. Itwill thus be seen that the apron is driven in the direction indicated bythe arrow in Fig. 14. The purpose of this apron will be apparent fromthis figure from which it will' be seen thaty chaff and occasionalkernels of grain passing out therewith are delivered to the apron 41 andcarried by it into the receiving hopper. Thus the grain and chaff whichwould otherwise be wasted are put into the bale with 'the straw.Therefore, substantially the entire nutrient value of the vegetation isbeing retained for future use.

. Another sprocket wheel, indicated by the numeral 50, is mounted onshaft 3 and has a sprocket chain 5| passing thereover and connecting itin driving relation with a sprocket wheel 52 mounted on a shaft 53 andsecured thereto. A sprocket 54 is mounted on the shaft 53 and isconnected to the sprocket 55 by the chain 56. The sprocket 55 is carriedby the knotter'shaft 51 which operates a suitable knotter mechanism 56in which there is no novelty. Any one of several mechanisms may be usedfor this purpose.

A- needle arm 59 is illustrated as being pivotally connected to the topand bottom of the discharge end of the tubular member I and is shown ascarrying the needle 60 through an opening 60a in the side of the tyingchamber. In Fig. 11 the needle 60 is shown as extending all the waythrough this chamber and as carrying the twine to position to be engagedby the knotter element. An old and well known mechanism is provided inconjunction with the knotter element for carrying the twine to positionto be gripped by the knotter. Since this is well known structure, nofurther mention need be made thereof in this connection, the operatingmeans being indicated in Figs. 8 and 12 by 59a, 58h, and 58C. A twinecontainer 6| is mounted on the discharge end of the baling mechanismadjacent the needle arm and holds one or more balls of twine to be usedin tying up the grain, straw, or the like, in a manner already familiarto anyone acquainted with binders. The essential difference between thestructure shown in Fig. 17 and that shown in the other figuresillustrating this form of my construction is that this structure isprovided with a pair of needles instead of one and with a pair ofcooperating knotter elements. Also, it will be understood that therewill be two twines fed from the twine holder 6|, one going to each ofthe needles 60, a suitable adjustable tension device being provided foreach.

Reference will now be made to Figs. 8, 10, and 12 for the description ofthe operation of the needle The sprocket 55 runs freely on the shaft 51except when the clutch 62 is operated to cause clutching of the sprocketto the shaft. When this takes place, the bevel gear 63, carried by theshaft 51, causes rotation of the bevel gear 64, carried by shaft 65,resulting in operation of the knotter mechanism and actuation of thecrank arm 66, pivotally connected to the links 61 which are in turnpivotally connected to the brackets 66,' integral with or secured to theneedle arm 59, and cause actuation thereof. As is well understood, theneedle arm 59 dwells for a time 4in the position shown in Fig. 8 whilethe vegetable matter collects in the collection chamber preparatory tobeing pushed out into tying position. In order that the bale may be tiedtightly, it is important that it be compressed upon opposite sides.Therefore, I have provided an arm 1|), carried by a shaft 1|, andarranged to swing in substantially the same plane as the needle. A crankarm 12 is secured to the shaft 1| and therefore actuates this shaft andthe outer compressor arm 10 when it is itself actuated by the link 13.This link is made up of a pair of relatively slidable elements 13a and13b which are drawn toward each other by a spring 13c, as shown clearlyin Fig. 10. A heavy spring 14 furnishes resilient compressible meansconnecting the two elements 13a and 13b so that the compression of thebale will be substantially uniform at all times. 'Ihe freev end of therod 13b is connected to the crank arm 3l so that it will besimultaneously actuated with the harpoons 36;4

'thus compressing the bale from opposite sides.'

simultaneously.

Rigidly connected to the shaft 33 is an arm 15 which engages a lever 16(see Fig. 10) pivoted at 11 upon a convenient portion of the frameworkof the apparatus. This lever has an arm 18 extending upwardly intoproximity to the -clutch 62 and the dog 19 of the latter is released bythe vlever when the crank arm 32 is actuated to cause cam 15 to actuatelever 16. It will thus be seen that, by virtue of the connection of thevarious parts, their motions will Abe synchronized so that the partswork in proper sequence.

As shown in Fig. 1'1, and also in Figs. 1, 2, and 3, this constructionmay be provided with a plurality of needles 60 and tying mechanisms 58.Since this duplicate structure is no diii'erent from and operates in nodifferent way than the single structure described above, with the singleexception that it makes use of two twines and puts two bands around thebale, no further description of this feature will be given. Referenceisv also made to the fact that the needles may be swung in planespassing vertically, or substantially vertically, through the tyingchamber. It is not thought necessary to make further reference to such aconstruction.

Referencewill now be made to Figs. 1 to 7A, inclusive, for thedescription of certain features of the construction which have not beendescribed in the foregoing.

In this construction there are several maior departures from theconstruction already described and chief among these is the arrangementofthe auger II to reciprocate along the shaft y3. This auger serves toforce therstalks into the baling chamber, arrange and compress themtherein, and then withdraw so as to permit'the grain compressors toswing inwardly and compress the grain sufllciently so that the needleshave substantially a clear channel to pass through in tying the bale.These compression members produce a high degree of compression at thelines where the twine is placed, thus insuring that the bands will betight and that they willnot slip oif the bale. The reciprocation of theauger is caused by means of links 8|A and 82 which are connected to thecrank 83, forming a part of shaft 8l. On this shaft is a'sprocket overwhich passes the sprocket chain 85, the latter also passing over asprocket mounted adjacent the right hand end of shaft 21. On the extremeright end of this shaft 21 is a clutch 86 having an arm 81 which engageswith a pair of stops 88 and 89. The stop 88 is actuated in one directionby the link 90 which is connected to a lever 9| pivotally mounted uponone side or the machine and engageable by an arm 92 carried by the shaftI6 of the bale measuring devies I5. From this it will be seen that eachtime the device |5 rotates a complete turn, the link 90 will be pulledto remove the stop dog from in front of the arm 81. Clutch 88 will thencause a driving connection between shaft 21 and the sprocket thereonover which the chain passes. Therefore, the crank shaft 84 will berotated and the crank 83 will cause reciprocation of the auger, asheretofore indicated. This half rotation of the clutch 86 and the crank83 causes withdrawal of the auger from the grain compressingcompartment. Carried by the shaft 84 is a cam 93 which engages the arm94, rotating the shaft 95 and swinging the arm 96 which is looselyconnected at^91 with the arm 98 (see Fig. 4). This latter is integrallyconnected with the shaft 99 which carries the stop arm |00 with which isconnected a spring |0| which serves to swing the arm |00 into positionto be engaged by the clutch operating arm |02 of the clutch |03.

'I'he stop arm 88 has been referred tc as stopping and releasing arm 81of clutch 86. The arm 89 is also so positioned that it is engaged by thearm 81 and stops `the rotation of clutch 86 after it has travelled ahalf revolution. This arm 89 (see Figs. 3 and 4) forms a part of or iscarried by the shaft |05 suitably mounted in the framework ofthe'machine and is given a partial rotation by the shaft |05 when thelatteris moved by the arm |06 when engaged by a projection on the faceof clutch |03. When this projection |01 (see Fig. 4) strikes arm |06,shaft |05 is rotated in its bearings, causing stop arm 89 to be carriedout of the way of clutch arm 81. The clutch is then permitted to makeanother half turn, bringing arm 81 into contact with stop 88. During therst half rotation of the clutch 86 and shaft 21. the auger is Withdrawnto the position shown in Fig. 2A by the links 8| and 82 and, during thesecond half rotation of the clutch and shaft, the auger is movedforwardly to the position shown in Fig. 3.

In Fig. 4 is shown somewhat in detail the control mechanism for a clutchillustrated in Fig. 2. This clutch ||0 is mounted on the lower end ofshaft A gear l I2 on theupper end of this shaft meshes with gear I2 onshaft 21. This connection serves to drive the shaft I and, from this,through clutch I| 0, the chain ||3 is driven. This chain passes over asprocket wheel mounted on the shaft 65 and causes actuation thereof.

This shaft serves as the driving means for the knotter mechanism andcarries at its two ends vthe cranks 66. The connection to and operationof the needles will be'obvious from the description given above inconnection with Figs. 8 et seq. 'I'he needles used in my constructiondiffer somewhat from the accepted form for same in that there areprojections on the inner side of cach needle which tend to hold thetwine away from the body of the needle and permit the tucker to get holdof the twine H6, the latter being held v away from the inner face of theneedle, as illus- Y trated in Fig. 7. Fig. 7A shows that the top ofprojection ||1 is bevelled or curved to cause the twine to slide overthe top face of the needle, in position to be engaged by the tucker. l

An arm ||8 is pivotally mounted in the bracket ||9 carried by the needlearm 59. A spring |20 vtends to swing the arm ||8 into the extended amasthe operation is being completed. The amount of twine drawn out by thearm ||0 is preferably between one-fourth and one-half enough for thetying of the bale, the remainder of the twine being drawn out by thebale as it is built up. An arm |2| projects outwardly from the frame ofthe machine and has a dog |22 pivoted thereon, said dog being actuatedby means of a spring |23, as is apparent from Figs. 2A and 3. The arm II0 has a short arm |24 projecting therefrom which engages with the' dog|22 to cause outward swinging of the arm ||0, as illustrated in Fig. 3.It will be obvious that when the surplus twine ||0 is taken up and thearm ||0 is swung in close to arm 50, arm |24 will be swung past dog |22and will be in such position that when the needle goes in for the tyingof the bale, the end of arm |24 will engage the dog |22 and cause it tobe turned on its pivot, stretching the spring |23'. When the needle 60swings in the opposite direction, toward the position illustrated inFig. 3, the end of the arm |24 engages the dog |22 and this causes thearm ||0 to swing forwardly into the position illustrated in Fig; 3, thusdrawing out twine for the starting of the next bale, though the amountdrawn out may be regulated by adjusting the length of the arm. A bale isnot discharged immediately upon completion but is retained in positionto serve as an abutment for the next bale during vat least the earlypart of the process of formation thereof. v

We will now turn to clutch |03 in the upper left portion of Fig. 3 andthe lower left portion of Fig. 4. The crank arm 20 is carried by theloose part of the clutch |03 and has a crank pin |20 on its outer facewhich is connected in driving relation with the link |23. It willtherefore be apparent that as the clutch is driven by the shaft 21, thelink |29 will be caused to reciprocate, thus transmitting motion to thecrank arm 12, the outer compressor arm 10, and the crank arm |30. Links|3| connect the crank arms |30 to the crank arms |32 which turn aboutthe shafts |33 (see Fig. 1). Stalks compressor elements or jaws |34 areactuated by the cranks |32 and swing into position between the needles60, as illustrated in Fig. 2A. A strong spring |35 is anchored at oneend to a frame element, as shown at |36, and at its opposite end isconnected by an eyebolt |31 or otherwise to the crank arm |30. As shownin Fig. 3, this crank arm has a projection from one side thereof,denoted by the numeral |38, to which the eyebolt |31 is connected. Asthe outer compressor arms 10 swing inwardly, the link connecting spring|35 to eyebolt |31 passes the end of shaft 1|. When this happens, thespring is at its greatest operative length and it tends to shorten asthe arms 10 continue to swing inwardly. This spring |35 thereforeassists in swinging the arm or arms 10 in to compress the bale, and, atthe same time, helps to swing compressors |34 -in against the stalks tocomplete the compressing thereof preliminary to tying.

We will now return again to clutch |03 and we see that as this clutchrotates with the shaft 21, the dog |02 strikes the stop |40 and releasesthe clutch so as to disconnect the driving relation between the clutchparts. When this happens, the link |23 stops, leaving the compressorarms 10 in their innermost position. It will be seen that at the sametime the gates. or compresser members |34 will be in the positionsshowninFlg. ZAandthebalewillbefully compressed. At this time, theneedles 00 pass in through the openings 00a carrying the twine to theknotters so that the bale will'be tied. Just as the gate or compressormembers start to come in, the auger is withdrawn so as to clear thespacefor the inward swinging ofA the compressor members. In the relativepositions occupied by the compressor members and the needles,substantially all of the straw will be out of the way -oi the needles sothat they will have a substanmuy clear path through the chamber andthere will be very little resistance to the passage of the needles tothe tying position.

Release of the clutch dog |02 from stop |40 is accomplished by a cam |45striking arm' |40 which is integral with or connected to shaft |41, ofwhich stop |40 forms a part. A spring |40 actuates stop |40 intostopping position. It will be seen from Figs. 2 and 5 that cam |45 iscarried by shaft which also has mounted thereon the sprocket |40 overwhich passes the chain ||3,referred to above. In a casing surroundingshafts 3 and 21 is a worm gear connection be` arm |5rto be engagedby aprojection |55 on an arm |50. A' stop |51 limits the swinging of arm |52in one direction. A spring |53a. coiled about shaft |53 serves tonormally retain stop |5| in stopping position. y

A guard |58 is secured to the collar |50 connected to.sleeve l0 andtherefore reciprocates therewith as the auger is moved back* and forth.The opposite end of the guard is suspended by any suitable means, shownas a shaft |00 passing through a pair-of arms |6| suspended from `ashaft |62 (see Fig. 4). This mounting permits the guard to reciprocatefreely with the auger. It is apparent that the guard will prevent theaccumulation of stalks upon the shaft 3 and links 8| and 02. Y

Reference has been made above to a tucker and this is common to both ofthe structures illustrated in Fig. 1 and Fig. 10. However, in Fig. 1Athis has been illustrated in connection with the double form shown inFig. 1. In Fig. l, the cam 50a is shown in edge view while, in Fig. 1A,it is shown in perspective and as being carried by the shaft 65. Thiscam cooperates with the lever 50h in actuating the link 50c which isconnected to the tucker hook |03 pivoted upon the bolt |64. An arm |65is rigid with the hook V|53 and from this extends a link |66, the latterbeing operatively connected with the other tucker hook |01 to causeoscillation thereof about its pivot |60. A spring |09 causes movement ofthese hooks about their respectivepivots into inoperative positions.When the needles 00 come into tying position, the cam 50a comes aroundand engages lever 58h, rocking same about its pivot |10 and causing thetucker hooks |03 and |61 to swing downwardly and forwardly closelyadjacent the needles 50 to pick up the twines ||0 The cycleof operationwill be next taken up and explained in connection with Figs. 1 to 6,inclusive. We will assume the parts to be in the positions illustratedin Figs. l, 2, and 3 and that the drive belt 6 is driving pulley 1 andshaft 3.

Now if vegetable stalks enter the receiving hopper, they will nd theirway to the auger and will be pushed forwardly thereby into thecollecting chamber where they will be given a spiral arrangement byvirtue of the rotation of the auger These stalks will be piled upagainst the twines I I6 and the building up of the bale will commence.As thebale is formed, it is pushed past the metering device I5 and thetrip 92 turns around with the shaft I6 until it moves the lever 9|farenough to release the stop 88 from the dog 81, thus permitting theclutch 86 to function. As a result of this, chain 85 is driven and thisresults in rotation of shaft 84. Rotation-of this shaft causesretraction of the auger Il, thus making room for the compressors |34 toswing in from above and below, as indicated in Fig. 2A, so as to placepressure upon the bale closely adjacent the parts where the needles areto pass through in carrying the twine around the bale. As indicatedheretofore, the shaft 21 rotates continuously with the shaft 3,

' thus furnishing rotary motion to the clutches |03 and I|0. Rotation oftheshaft 84 causes the trip 83 to actuate the train of connection comf`prislng 84, 95, 85, 91, 88, 98, Aand |00, thus releasing the dog |02,and throwing in the clutch |03 to cause the driving of the crank varm 28and the link |28. Actuation of'this link causes the arm or arms 10 to beswung inwardly against the end of the bale. Simultaneously. with theswinging of these arms, the crank arms |30 are turned and the links |3Icause the compressor members |34 to be swung inwardly, as indicated inFig. 2A.

When dog 81 is released, clutch 86 turns onehalf rotation until the dogstrikes the stop 89.y

This disconnects the clutch and stops the driving of the shaft 04,leaving the auger in retracted position. However, clutch |03 continuesits rotation and the projection thereon, which cooperates with arm |06,causes the rocking of this arm and of shaft |05, which results in stop88 being withdrawn from in front of dog 81. This will permit thecompletion of rotation of the clutch 86 and shaft 84, carrying the augerI back into position to cause arranging and compressing of the vegetablestalks.

At just about the timeV the compressors` |34 have reached theirinnermost limits, the projection on arm |56 engages arm |54 and causesstop |5| (see Fig. 6) to be retracted from in front ofvdog |50. Thispermits clutch III) to function and to cause driving of chain I|3 which,as will be seen from Fig. 3, causes operation of the knotting mechanism56, shaft 65, and the needle mechanism connected thereto, which resultsin the twine being carried across the back face of the bale and Vtied soas to complete the baling operation. The needles are actuated by shaftand enter the baling compartment while the compressors |34 are holdingthe stalks compressed and they are withdrawn before the auger is againmoved forward. y

With completion of the-bale tyingk operation and withdrawal of theneedles, the compressors |34 and arms 10 are returned to inoperativeposition, illustrated in Fig. 2. The actuation of the needles andknotters requires but a single tripping of clutch ||0, while cycles ofauger and members 10 and |34 require two trippings of clutches 86 and|03, respectively.
